Keyboard –
This is a component that comes in direct contact for you with your PC.
The mechanism of keyboard converts a key cap’s movement into a signal sent to the
computer. The most common key mechanisms are “
capacitate
” and “
hard
contact
”. Capacitate keyboard has a spring that causes the plastic and the metal
plunger to move near two pads that have large plates (plated in tin, nickel, and copper).
These pads are connected to the keyboard’s printed circuit board. Hard contact
keyboard causes the key cap to collapse a foam rubber dome that presses against a
sheet of plastic on the bottom of which is metallic area connected to the rest of the
keyboard’s
circuit board.

with the popularity of Windows, a mouse is becoming standard equipment on all PCs,
as well. The “
Trackball

keyboard. “

which you press either your finger or special light pen to control the software, are too
tiring to use for any length of time.
